Lecithin is a necessary component of every cell in the human body. Considered a keystone in the construction of cells, it prevents the hardening of cell membranes. Healthy cells lead to a healthier body. In addition to the cardiovascular benefits, there are indications that it helps to restore livers that have been damaged as well as working with neurological functions such as memory to improve the brain's effectiveness.

Since lecithin is essentially fat, it can act as a protective sheath throughout the body to protect and strengthen membranes and prevent detrimental debris from sticking. Patients suffering from atherosclerosis often start a regimen of lecithin in an effort to reverse the condition's effects.

As a tool for heart health, lecithin also works to reverse and prevent damage that may arise from coronary artery disease. Preventing cholesterol and other fats from sticking is a vital function for the overall health of anyone with cardiovascular afflictions. Improved circulation as a result of supplementation helps to prevent blood clots and maintain the health of the liver. Lecithin is also believed to have positive effects in the repair of livers damaged by any number of conditions, including excess consumption of alcohol or other toxins.

Lecithin can be used as a tool to help the body recover from previously identified conditions or shortcomings, as well as for preventive purposes. Individuals with a history of any neurological or cardiovascular condition may take lecithin as a supplement to lessen their chances of a recurring issue. Additionally, those with a genetic background indicating certain conditions may occur could take lecithin for preventive reasons.
